I have never taken steroids and never will. BUT I know and understand that in the right circumstances, with the right knowledge on how to supplement such a product their dangers and setbacks can be controlled. Some factors like acne are unpreventable however, common dangers associated with steroids like tumors are not always the case. Most problems occur with steroid use due to lack of knowledge. But when consumed by someone who actually knows what they are doing the setbacks are reduced somewhat. But steroids will stunt growth, so only if you are at least 21 should you even THINK about using steroids.
